How a crash looks like in Flytrex

Flytrex is a great, cheap and lightweight tool to help, to a certain extend see what may have gone wrong. It doesn’t however include input from your transmitter.

An example below from a crash, speed and altitude has a sudden drop within 2 secs. It’s regardless there is no other logging as the crash was caused by a broken propeller mid flight after reviewing the onboard video footage.

Comparing, a normal flight does not have erratic lines or a sudden fall in speed and altitude.

Simple analyzing of these cannot really help in determining if it was pilot input error but does help somewhat.
